The correct statement is C. Alkali and alkaline earth metals dissolve in liquid ammonia to form ammoniated electrons and ammoniated metal ions. For alkaline earth metals, hexa-ammoniates like $[M(N{H}_3{)}_6]C{l}_2$ can be recovered upon evaporation. The blue color is due to ammoniated electrons, not cations. Alkali metals can be recovered.
